alright, I wouldnt even know where to start but porting it myself, leave it to someone else.....
So spend the money on different heads or porting the same 5.3 heads is the question?

 

Porting isn't cheap unless you know somebody..

and you can get a set of 243s for /$350-500 bucks. I saw some on ls1tech the other day the guy only wanted $350 for them.

and the 5.3 heads have much smaller valves so even if you ported them, the valves would still hold you back.

 

There's no reasont pay some moron more than $400 for a set of used 243's. I bought brand new never used 243's with yellow valve springs from Patriot for $425.

 

Gunnar sells them like this all day, day in and day out.

 

The cheapest they have on there website is $645 for blank LS6 OEM castings. That sounds awful cheap for a brand new complete set to me.

 

nope...
like hirdlej said, you can get them brand new, completly assembled for $450 from patroit.

 

That is a stinkin' good deal!!

I wonder why they don't have it posted on there website? That would save a lot of people some money.

 

I can take pictures of them if you don't believe me. I just got mine last week. They are NEW, not rebuilt. GM valves and yellow LS6 springs. You can't go wrong. I hate buying used heads because all the guys who have 243 heads think they're worth gold and they slap that "corvette tax" on there. Buy new, then you know they've never been molested, dropped, over heated, over revved, etc etc.

 

Oh and I should adjust my price, I paid $425 but they were $450 after shipping

 

Nah, I believe you thats a really good deal, but already got some p&p'd 243s I'm gonna put on my truck.
